Three things are required to enable wake-on-usb: 1. 5V to USB ports should be enabled in S3. 2. ASL file needs to have appropriate wake bit set. 3. XHCI controller should have the wake on attach/detach bit set for the corresponding port in PORTSCN register. Only part missing was #3. This CL adds support to allow mainboard to define a bitmap in devicetree corresponding to the ports that it wants to enable wake-on-usb feature. Based on the bitmap, wake on attach/detach bits in PORTSCN would be set by xhci.asl for the appropriate ports. BUG=chrome-os-partner:58734 BRANCH=None TEST=Verified that with port 5 enabled, chell wakes up from S3 on usb attach/detach.
